SERPens vs DataForSEO
Priced for agencies, shaped for pipelines.
Response fields
| Field | SERPens | DataForSEO |
|---|---|---|
| Organic results | Yes | Yes |
| AI Overview | Yes | No |
| Knowledge panel | Yes | Yes |
| People Also Ask | Yes | Yes |
| Related searches | Yes | Yes |
| Sitelinks | Yes | Yes |
| Result source field | Yes | No |
| Pagination flags | Yes | Yes |
On our side, sitelinks, knowledge panel, People Also Ask and related searches arrive with the AI Overview endpoint, not with the plain organic call — one request returns all four alongside the overview and the results.
Compared against dataforseo.com, checked 2026-08-26. Blank cells mean the vendor did not document the field, not that it is missing.
Price
| Provider | Per 1,000 | Notes |
|---|---|---|
| SERPens | $1.16 | 100 free calls a month, no card |
| DataForSEO | $0.60 | $50 minimum monthly commitment |
Prices move. Both figures carry the date they were checked, and neither is a quote.
Surface
| Provider | Documented verticals | Response style |
|---|---|---|
| SERPens | 2 | camelCase |
| DataForSEO | — | snake_case |
We cover two surfaces: web search, and web search with the AI Overview. That is fewer than most providers here, and it is a choice rather than a roadmap gap — one surface measured continuously and published in public is worth more than twenty nobody checks.
When DataForSEO is the better choice
DataForSEO is built for agencies running large keyword sets and prices accordingly, with a monthly minimum. There is no free tier to try it on. If you are past the minimum anyway, the per-call price is hard to beat.
What you get here that you do not there
A dedicated AI Overview endpoint returning Google's answer and the sources it credits, which DataForSEO does not document. And a public measurement record: 4,185 queries run weekly through the same endpoint, with 50.8% carrying an overview as of 2026-W36.
Nobody else in this table publishes what their API returns. Ours is written out in full.
